Absorption heating and cooling equipment

Abstract

The invention relates to an absorption cooling and heating device which utilizes the evaporation heat generated when the refrigerant evaporates in the evaporator to cool or heat, and absorbs the vapor of the refrigerant by the absorption machine. The absorption cooling and heating equipment of the present invention comprises: a first heat transfer tube, which is arranged in an evaporator, flows with cold water or warm water, and is formed into a curved shape so that both ends are fixed on a tube plate located at one end of the evaporator; A heat transfer tube, provided in the absorption machine, through which cooling water flows, is formed in a curved shape so that both ends are fixed to a tube plate located at one end of the absorption machine. In the present invention, when the heat transfer tube is heated by the refrigerant vapor, the heat transfer tube will not be deformed laterally, but will expand smoothly along the length direction, and the tube plate only needs to be equipped at one end of the evaporator and the absorber, so the structure is simple and the manufacturing cost can be saved .

Description

technical field [0001] The invention relates to cooling and heating equipment for adjusting indoor cooling and heating, in particular to an absorption heating and cooling equipment which utilizes the evaporation heat generated when the refrigerant in the evaporator evaporates to cool or heat, and makes the absorption machine absorb the refrigerant vapor. Background technique [0002] Absorption cooling and heating equipment uses the principle that the liquid solubility of refrigerant gas changes with temperature and pressure. Usually, LPG, LNG and other gases are used as heat sources, and the absorption solution and refrigerant are used to achieve a circulating cooling and heating process. Such absorption cooling and heating equipment is equipped with an absorption machine and a regeneration machine to replace the compressor of the existing vapor compression heating and cooling equipment that uses electricity as energy, and utilizes disposable heat energy, thereby reducing th...

Problems solved by technology

However, there are the following problems: not only the heat transfer tubes, but also the evaporator and the absorber must be made into a ∩ shape, and a high-temperature regenerator is installed inside it, so the two ends of the evaporator and the absorber must still be equipped with tube sheets, so the structure becomes complicated, and the state of piping connection when piping is connected at the end of the heat transfer tube also becomes complicated
